Cull where your photos live.

Photo and video culling cockpit that browses every storage backend you actually use — local drives, NAS, SFTP, WebDAV, Dropbox, OneDrive, Google Photos, iCloud, and USB-connected phones — without downloading or consolidating first. Ships with on-device AI: semantic image search ("sunset over water"), face detection, closed-eye and NSFW flagging, and smart auto-stacking by visual similarity, capture-time bursts, or face identity. No subscription, no cloud uploads, no model training on your photos. Mac, Windows, and Linux from one license — Free, Standard $99, Pro $179, perpetual.

Future product

More to come from the studio.

Aviastone's roadmap includes additional desktop tools built around the same principles: ownership, privacy, cross-platform support, and a fair one-time price.

TBD

What we believe.

🔒

Your files stay on your machine

We build desktop software, not cloud services. Your photos, documents, and work product never leave your hardware. AI features — when we ship them — run on your device, not on our servers; we never train models on your work and never collect telemetry. This isn't a feature — it's the default.

🎯

One-time licenses, not rent

Software you can buy once and own forever, with free updates within a major version. Subscriptions are the right model for some things — they're not the right model for a tool you depend on every day. You shouldn't lose access to your own work because you stopped paying rent.

🌍

Cross-platform from day one

Every Aviastone product runs on Mac, Windows, and Linux from the same codebase. One license, every platform. We don't believe in punishing customers for their hardware choice or hiding features behind platform tiers.

📐

Built by people who use the tools

Every product we ship is built because we needed it ourselves and couldn't find a tool that did the job right. We're not chasing markets — we're solving our own problems and inviting people who share them.
